Summary

Anterior cruciate ligament injury is a common complication of posterolateral tibial plateau fractures. The posterolateral tibial plateau fracture is a special type of plateau fracture. Due to its special location, it is difficult to perform open reduction and internal fixation, which is a difficulty in orthopedics.

Abstract

Purpose

Objective

to investigate the clinical effect of arthroscopic treatment of anterior cruciate ligament injury combined with posterolateral tibial plateau fractures.

Methods

10 patients with anterior cruciate ligament injury combined with posterolateral tibial plateau fractures in our hospital were treated between February 2015 and October 2015, and the clinical data were retrospectively analyzed. There were 5 males and 5 females, with an average age of 43.5 years (range,16-58 years). Among them, 2 cases of anterior cruciate ligament tibial avulsion fracture, arthroscopic anterior cruciate ligament avulsion fracture reduction Ethibond fixation and posterolateral tibial plateau fracture reduction and bone grafting. The remaining 8 patients in arthroscopic cruciate ligament reconstruction with autologous hamstring tendon transplantation, posterolateral tibial plateau collapse fracture reduction and bone grafting. In 2 cases, because of the large area of articular surface collapse, the cannulate screw or proximal tibial anatomic locking plate fixation was performed. All patients were performed immediately after operation the femoral head four muscle, leg muscle pump and straight leg raising function training, postoperative 3-5 days hold double limb weight-bearing ambulation.

Results

10 patients were followed-up for 9-13 months (an average of 10.9 months). 10 patients were all healed well, and the Lysholm score of knee joint function was 84-98 after operation for 9 months, with an average of 90.8. Among them, 3 cases were excellent, good in 6 cases, general in 1 cases. Good rate 90%.

Conclusion

Arthroscopic treatment of anterior cruciate ligament injury combined with posterolateral tibial plateau fractures with less trauma, which can deal with joint injury, and can obtain good reduction and postoperative functional advantages of fast, good effect, less complications and recovery. Further study is needed for the proper evidence based use and application of this method.
